SUGABrCUTTING ATTACHMENT FOR SUGAR-CENTRIFUGALS.

To all whom it may concern:

Be it known that I, Gnoncn Vrvns, a citizen of the United States,residingat Thibodauiz, in the parish of Lafourche and State of-Louisiana, have invented anew and useful Sugar-Cutting Attachment "forSugar- Centrifugals, of which the following is a specification.-

The present invention relates to improvements in cutting attachments forsugar centrifugals, and the primary object of this invention is theprovision of a device adapted to be normally held in the position. to be'moved vertically within and adjacent to the peripheral walls of a sugarcentrifugal, and by means of a .spring actuatedrod to have a cuttingtool disposed against the wall, to remove the crusted sugar therefromduring 'the rotation of the centrifugal receptacle.

A further object of this invention is the provision of a cutting deviceadapted to be attached to a centrifugal supporting frame and be movedvertically into and out of the centrifugal receptacle, the same being ashaft having mounted upon its lower end a cutting or scraping tool whichnormally exerts a tension to engage the inner peripheral wall of thereceptacle in combination with a weight actuated means for moving saidcutting or scraping tool or rod vertically up and down within thereceptacle.

- A still further object of the invention is the provision of means forlooking the cutting or scraping device out of engagement with the wallof the centrifugal receptacle, and yet in such a position to be readilyplaced in operable relation thereto when desired.

lVith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it changes in the precise embodiment of inventionherein disclosed can be made within the scope of what is claimed withoutdeparting from the spirit of the invention.

In the .drawings-Figure 1 is a vertical central sectional view through acentrifugal and frame, showing the scraping device in operable relationthereto,- the same being shown in dottedlines when operating near thebottom or lower portion of the walls thereof. Fig.2 is an enlargeddetail top elevation of the cutting blade and operating being understoodthat Specification of Letters Patent. Patented Dem 2 6, 1911,Application filed August 12, 1911.

mechanism showing a portion of the receptacle and supporting platform.Fig. 3 is a detailed perspective view of the cutting and scraping bladewith a portion of its carrying rod adjacent thereto. Fig. 4. is a cross.section through the main shaft showing. the

mounting of the spring thereupon.

Referring to the drawings, thenumera-l 1 designates: the .main frame,platform 2 adjacent to the mouth of the centrifugal sugar receptacle 1,which is operably connected tothe vertical shaft 3 in the carrying theusual manner, the upperend' thereof being ournaled in the transverseplate or beam 5, 7

to which is connected thesuper-structure 6 of the present invention.

Connected to the rim 7 and also upon one side and the upper side of theplatform 2 as clearly shown in Fig. 1 is a loop Sand plate 9, whoseouter end, 10 'is provided with a bearing and projects beyond theplatform 2 and beyond the peripheral edge of and within the receptacle.

Mounted for vertical and oscillatory 30 movement within the terminal 10of the plate 9 is a shaft 11, which passes upwardly and through the beamv5 and within the super-structure 6, as clearly shown in Fig. 1, are therods 12 and 13 and the plates and 35 braces 14 and 15, constituting aframe for properly supporting the shaft 11 and its locking device aswill presently appear.

The shaft 11 passes through the outer end .of the arm or plate 15, asclearly shown, and in order to limit the upward movement of said shaftis a sleeve 16 mounted below the plate 15. Connected to theupper end ofthe shaft 11 at 17 and passing through the pulley sheaves 18 and thesuper-structure 6, is a flexible cable. 17, whose other end is connectedwith a cylindricalweight 19 disposed to travel as shown .in full anddotted lines in Fig. 1, which weight is sufficiently heavy to. normallyretain the parts in the position shown in full lines .in Fig. 1.

Mounted upon the lower end of the "sluift 11 and normally within thereceptacle 1 is the cutting and scraping tool 20, which as clearly shownin detail in Fig. 3, is removably attached to the lower'end of the shaft11 and is provided with the removable cutting or scraping blade orpoint- 21, the plate 20 being of a flexible metal so as to normallyexert aspring tension upon the cutting point- 21 when ,in engagementwith the side-of the receptacle 4;.as shown in dotted lines "Fig. 2.-The plate 20. is provided with curved upper corner 21' so as to deflectthe freed or cut sugarfrom the body of the scraper or cutter as thereceptacle 4 is rotated during thescraping and cutting action. w-Connected dependingly from the under side of the plate 15 are the twoposts or pins .22 and '23, respectively, which provide ameans forsupporting the catch 24, so that 7 its engaging end 25 will be normallyin the path of the handle 27 connected to the shaft 11, when such handleis turned to inoperative position to cause the cutter or scrapingbladeto assume the position as shown in full.

lines in.Fig. 2, the spring 26 mounted upon the lower enact the pin 23and normally holding the free'end of said-shaft in upward 27 whenassuming the position as shown in full lines in Fig. 2, locking the saidscraper inthe position as shown in full lin'es so that itwill notcontact or engage the Walls of the receptacle during the ordinarycentrifugal action thereof. By this means the spring 28 remains atthesame relative position while the movement of the shaft 11 will notchangeits position as the terminal 28' will slide within thegroove 11-in the. shaft 11] and therefore permit the vertical adjustment of saidshaft, the spring at all times exerting the proper and desired tension.To

assist the spring 28, which might not be sufficiently strong to hold thecutter in proper contact with the walls of the centrifugal, the operatormay grasp-the handle 27'and push or pull it to' assist said spring andthus eirert a greater pressure of the cutter upon the walls.

-. connection with the drawings, it is evident that when the device isnot in use that it will assume the position as shown in Figs. 1 and 2 infull lines. To operate the device it is simply necessaryto release thehandle 27 from the catch 24 so that the spring 28 will oscillate theshaft 11 to bring the-cutting point 21 into engagement with the innerwall of the receptacle 4, the parts heing-then in the position shown indotted lines in Fig. 1. As the receptacle at is being rotated, and thepoint 21 is placed in engagement with the wall and held thereto by meansof the spring 28, sufficient friction is exerted upon the cutting point21 of the.

movement upon the shaft d1,assisted manually'when necessary by-theoperator, to raise the same and that by the time the scraper has movedfrom the dotted position' as shown-in Fig. 1 to that in full linestherein, the entire 'wall of the receptacle will have been scraped, themanual assistance given the rise of the scraper during its operationpreventingany spiral cutting of the sugar from the centrifugal, thereby.insuring the cleaning of the walls entirely of theincrustations.

It will be seen that by this construction that the wall of thecentrifugal receptaclemay be cleaned without the necessity of -stoppingthe machine and scraping with knives as is the usual custom.
